3x-22+x=180
4x-22=180
4x=202
X=202/4
X=50.5
3(50.5)-22=129.5
5-.5+129.5=180
Answer:
<em>y = - </em>
<em> cos ( </em>
<em> x ) , y = cos ( 3x ) + 2 </em>
Step-by-step explanation:
<u><em>Image 1.</em></u>
The graph is reflection of cosine over x-axis and max is 3.5 ⇒ A = -
Period is ( 4 π ) ⇒ B =
There are no horizontal and vertical shifts ⇒ C = D = 0
<em>y = - </em>
<em> cos ( </em>
<em> x )</em>
<u><em>Image 3.</em></u>
The graph of cosine shifted 2 units up only ⇒ D = 2 , C = 0
Period of the given function is
⇒ B = 3
<em>y = cos ( 3x ) + 2</em>
The upper left quadrant is I (1), the upper right is II (2), lower left is III (3), and lower right is IV (4).
